NOTE: Also check intermediate connectors D-28, D-111 and F-
10 for loose, corroded, or damaged terminals, or terminals
pushed back in the connector. If intermediate connector D-28,
D-111 or F-10 is damaged, repair or replace the damaged com-
ponent(s) as described in GROUP 00E, Harness Connector
Inspection

P.00E-2

.

Q: Is the wiring harness between rear light (LH) connector

G-16 (terminal 1) and front-ECU connector A-07X
(terminal 8) in good condition?
YES : Replace the rear combination light socket (LH). Verify

that the taillights (LH) illuminates normally.

NO : The wiring harness may be damaged or the

connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary. Verify that
the taillights (LH) illuminates normally.

STEP 32. Check the taillight bulb (RH).
(1) Remove the taillight bulb (RH).
(2) Verify that the taillight bulb (RH) is not damaged or burned

out.

Q: Is the taillight bulb (RH) in good condition?

YES : Go to Step 33.
NO : Replace the taillight bulb (RH). Verify that the taillight

(RH) illuminates normally.

STEP 33. Check the ground circuit to the taillight (RH). Test
at rear light (RH) connector G-12.
(1) Disconnect rear light (RH) connector G-12 and measure the

resistance available at the wiring harness side of the
connector.

(2) Measure the resistance value between terminal 3 and

ground.

• The resistance should equal 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 36.
NO : Go to Step 34.

STEP 34. Check rear light (RH) connector G-12 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is rear light (RH) connector G-12 in good condition?

YES : Go to Step 35.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. Verify that the taillight (RH) illuminates

normally.
